Schaefer Jiffy Reefing allows an entire "slab" to be quickly removed from the mainsail to reduce sail area and power in
"heavy-air" conditions. With the mainsheet and main halyard eased, Jiffy Reefing lines pull the aft reef grommet
tight to the boom. A separate reef line attached to the forward reef grommet is then tightened, pulling the sail
tight and flat at the gooseneck. The halyard is then tightened and the mainsheet is trimmed with a new reduced sail
area. It is also possible to create a single line system with Schaefer's unique block selection.

Adjustable Jiffy Reefing Schaefer Sliders with welded bails, ride on boom mounted track to provide proper dead-end attachment
point location for and aft. The reefing line dead ends on the stainless steel bail, leads under the boom and up through
the reefing grommet in the sail. The Block version leads the line forward along the boom to a spar mounted jam cleat.
